So happy that the Sensei plotline is done with.
I was a little confused during the marathon, though, when Hikaru asked Chisato who she was. She's the one who Hikaru studied with (and the one who confessed to Hikaru!) in the previous volume. Definitely the same girl, and the other two girls with her were also in the study group. I just found that weird, like the scene in volume 4 never happened. (Not to mention the whole arranged marriage part later in this volume.)
I like how Izumi is growing both as a character and physically. He's still beautiful when he's acting and cross-dressing, but he has a really lovely manliness to him as well as the series goes on.
